The setting position can be a station of indoor personnel, and the setting temperature is a required temperature input by a target (indoor personnel) to be supplied with air. The orifice plate air supply mode is mainly used for meeting the personalized heat demands of indoor personnel. In addition, the area of orifice plate supply-air outlet is greater than the size of traditional wind gap and personnel's projection size on ground, under the unchangeable circumstances of amount of wind, the air supply speed is low, and personnel do not have the sense of blowing.

The accessibility calculation formula of the orifice plate air supply outlet to each indoor position is as follows:
wherein ,presetting an initial temperature for an orifice plate air supply outlet, +.>Presetting the temperature of an orifice plate air supply outlet>Air supply temperature rise value theta of orifice plate air supply outlet j A first temperature rise value of each position in the room, the first temperature rise value theta j Equal to the current temperature T of each position in the room j Initial temperature T with each position in the room 0 j Minus (minus) or (plus) the weight of the patient>The accessibility of the air supply temperature of the orifice plate air supply opening to each indoor position represents the contribution degree of the orifice plate air supply opening to the indoor temperature.

In the process of establishing a fixed flow field, the air supply openings of each pore plate are firstly heated at a certain preset initial temperatureAir supply, at this time, irrespective of the heat source, monitors the initial temperature T of each indoor position 0 j Then only the air supply temperature of one of the orifice plate air supply openings is increased toPreset temperature->Monitoring the current temperature T of each position in the room irrespective of the heat source j Dividing the first temperature rise value of each indoor position by the air supply temperature rise value of the orifice plate air supply opening>And obtaining the accessibility of the air supply temperature of the orifice plate air supply opening to each indoor position.
Further, the accessibility of the heat source to each indoor position is calculated as follows:
wherein ,θj A second temperature rise value theta for each position in the room j Equal to the current temperature T of each position in the room j Initial temperature T with each position in the room 0 j The difference is subtracted from each other,for average temperature rising value, ρ is air supply density, < ->Is the nth H Intensity of individual heat sources, C p Is air specific heat capacity, Q is air supply quantity of orifice plate air supply outlet, +.>The accessibility of the heat source to various indoor positions represents the contribution degree of the heat source to the indoor temperature.

Specifically, as shown in fig. 11 (b), if there is a sudden contaminant in the room, the target air supply mode is determined to be an air curtain air supply mode, and the air supply amount of the air curtain air supply port is calculated according to the contaminant limiting concentration, and the air supply amount of the air curtain air supply port is determined to be the target air supply parameter.
The setting position can be a station of indoor personnel, and the pollutant limiting concentration is the pollutant concentration limiting requirement input by an object to be blown (indoor personnel). The air curtain air supply mode is mainly used for blocking sudden pollutants or pathogen invading personnel areas or blocking the transmission of pathogens emitted by personnel to other areas, and mainly used for guaranteeing the health of the personnel.

Further, the specific calculation process of the air supply quantity of the air curtain air supply outlet comprises the following steps: the method comprises the steps of obtaining the strength of pollutants and the concentration of the pollutants at an air curtain air supply outlet; determining third accessibility of the air curtain air supply port to the target position to be supplied with air and fourth accessibility of pollutants to the target position to be supplied with air; and calculating the air supply quantity of the air curtain air supply opening according to the strength of the pollutants, the pollutant concentration and the pollutant limiting concentration at the air curtain air supply opening, the third accessibility and the fourth accessibility.
It should be noted that, the determining process of the third accessibility and the fourth accessibility is similar to the determining process of the first accessibility and the second accessibility, but only when the fixed flow field is established, each air curtain air supply port supplies air with a certain initial air supply concentration, and no detailed description is given here.
In addition, in a specific application scene, if toxic gas or pollutant emergency exists, and the situation is urgent, even if a user does not input pollutant limiting concentration, the embodiment of the invention can automatically calculate the air supply quantity of the air curtain air supply opening according to the default pollutant limiting concentration, and at the moment, if indoor personnel cannot escape, the indoor personnel can quickly return to the seat of the air curtain air supply opening, and the air curtain air supply opening can supply air based on the calculated air supply quantity so as to block the toxic gas and ensure the safety of the indoor personnel.
Therefore, in the air curtain air supply mode, the air supply quantity of the air curtain air supply opening can be calculated according to the formula so as to control the air curtain air supply opening to supply air based on the air supply quantity.
Further, if no abrupt contaminant exists in the room, determining that the target air supply mode is an orifice plate air supply mode, calculating the air supply amount of an orifice plate air supply port according to the contaminant limiting concentration, and determining the air supply amount of the orifice plate air supply port as the target air supply parameter.
It should be noted that, the orifice plate air supply mode can also ensure daily ventilation when no sudden air pollution or pathogen is released, and the air supply quantity of the orifice plate air supply opening can be determined according to the calculation mode of the air supply quantity of the air curtain air supply opening, and no further description is given here.

Based thereon, the method comprises: determining the vertical distance and the horizontal distance between the head of the target to be blown and the air curtain blowing opening according to the position information; calculating the equivalent diameter of the air curtain air supply outlet; and calculating the air supply angle of the air curtain air supply opening in real time according to the vertical distance, the horizontal distance and the equivalent diameter. The specific calculation formula of the air supply angle beta of the air curtain air supply opening is as follows:
wherein z is the vertical distance between the head of the indoor personnel and the air curtain air supply outlet, T s Is the air supply temperature T of an air curtain air supply opening j Is the temperature near the indoor personnel, V s Is the air supply speed of the air curtain air supply outlet, T s 、T j and Vs Can be measured by a sensor, g is the gravity acceleration, x is the horizontal distance between the head of the indoor personnel and the air curtain air supply opening, a is the turbulence coefficient, d is the equivalent diameter of the air curtain air supply opening,a and b are length information and width information of a rectangle corresponding to the air curtain air supply opening.
